PCS Features
The Cyclone V core logic connects to the PCS through an 8, 10, 16, 20, 32, or 40 bit
interface, depending on the transceiver data rate and protocol. Cyclone V devices
contain PCS hard IP to support PCIe Gen1 and Gen2, Gbps Ethernet (GbE), Serial
RapidIO
®
(SRIO), and Common Public Radio Interface (CPRI).
Most of the standard and proprietary protocols from 614 Mbps to 6.144 Gbps are
supported.
